Winding apparatus

ABSTRACT

A winding machine, such as a UNIFIL loom winder, manufactured by Leesona Corporation, Warwick, Rhode Island 02887, has a spindle assembly for receiving and rotating a bobbin, and a traversing assembly including a traversing member releasably threadedly secured to a traverse rod, during winding, for guiding a strand of yarn being wound onto the bobbin. Upon completion of winding, the traversing member is released from the traverse rod and the traversing member is returned to its starting point, the yarn is cut between the traversing member and the doffed, filled bobbin, and the cut yarn is engaged for winding onto an empty bobbin previously donned onto the winder. The traversing and spindle assemblies are driven by mechanism within a casing of the winder. This mechanism includes a continuously driven drive shaft connected by a clutch with a spindle shaft during winding, and disengaged at the termination of winding. A power take-off from the spindle shaft drives cams rotatably received on the spindle shaft for rotating and reciprocating the threaded traverse rod to provide the traversing member with builder and reciprocating motions. Lubrication of the rotatable cam and spindle shaft, and other portions of the mechanism within the casing, is provided by a rotating slinger which projects atomized lubricant upwardly through a duct and onto aprons of an upper duct from which the lubricant flows through channels and passages to lubricate the cam and spindle shaft. When the traversing member has been returned to its starting position, a cycling mechanism causes the clutch to again drivingly engage the drive shaft and spindle shaft whereupon the cycle is repeated.

Davis [57] ABSTRACT A winding machine, such as aUNIFIL loom winder, manufactured by Leesona Corporation, Warwick, Rhodeisland 02887, has a spindle assembly for receiving and rotating abobbin, and a traversing assembly including a traversing memberreleasably threadedly secured to a traverse rod, during winding, forguiding a strand of yarn being wound onto the bobbin. Upon completion ofwinding, the traversing member is released from the traverse rod and thetraversing member is returned to its starting point, the yarn is cutbetween the traversing member and the doffed, filled bobbin, and the cutyarn is engaged for winding onto an empty bobbin previously donned ontothe winder. The traversing and spindle assemblies are driven bymechanism within a casing of the winder. This mechanism includes acontinuously driven drive shaft connected by a clutch with a spindleshaft during winding, and disengaged at the termination of winding. Apower take-off from the spindle shaft drives cams rotatably received onthe spindle shaft for rotating and reciprocating the threaded traverserod to provide the traversing member with builder and reciprocatingmotions. Lubrication of the rotatable cam and spindle shaft, and otherportions of the mechanism within the casing, is provided by a rotatingslinger which projects atomized lubricant upwardly through a duct andonto aprons of an upper duct from which the lubricant flows throughchannels and passages to lubricate the cam and spindle shaft. When thetraversing member has been returned to its starting position, a cyclingmechanism causes the clutch to again drivingly engage the drive shaftand spindle shaft whereupon the cycle is repeated.

8 Claims, 6 Drawing Figures PATENTEDJUHN me ATTORNEYS WINDING APPARATUSThis invention relates to winding and, more particularly, to a highspeed winding machine.

As used herein the term yarn means any type of strand material, whethertextile or otherwise, and the term bobbin means any type of yarn packageor cop wound so that it may be readily moved from place to place, or acore on which the yarn is wound.

PRIOR ART AND REFERENCE MATERIAL The following Leesona Corporationpatents and patent application are incorporated by reference: US. Pat.No. 2,614,771, dated Oct. 21, 1952; US. Pat. No. 2,638,936, dated May19, 1953; US. Pat. No. 2,763,443, dated Sept. 18, 1956; and US. Pat. No.2,785,704, dated Mar. 19, 1957; and US. patent application Ser. No.36,126, filed May 11, 1970. These patents and application pertain to theUNTFIL loom winders of which Model 790 and 791 are of particularinterest.

The operation of the UNIFIL winders is well understood in the art and isdescribed in the reference patents. The entire operation is automatic.Empty bobbins are fed from a bobbin supply hopper and are automaticallydonned in opposed rotatable chucks. The end of the yarn passes through ayarn guide of a traversing member and is automatically engaged forwinding with the empty bobbin which is rotating during normal winding,as the traversing member is reciprocated back and forth by a threadedtraverse rod to which it is releasably secured. At the end of winding,the traversing member is released from the threaded traverse rod, thefilled bobbin is doffed, the supply yarn is cut, a new bobbin donned andthe traversing member is returned to its starting position to repeat thecycle. Drive and control mechanism within a casing of the winderincludes a drive shaft which is continuously driven by a belt driveoutside the casing. A clutch connects the drive shaft with a spindleshaft which carries one of the bobbin receiving chucks. A power take-offfrom the spindle shaft drives cams rotatably received on the spindleshaft for reciprocating and rotating the threaded traverse rod toprovide a to and fro, and a builder motion to the traversing member. Atthe end of winding, mechanism outside of the casing is actuated by thetraversing member to rotate a track rod which initiates release of arectangular rod to rotate and open the jaws of the traversing member.Such rotation of the track rod actuates a cycling mechanism driven bythe drive shaft within the casing, and actuates mechanism for releasingthe clutch between the drive shaft and the spindle shaft, and initiatesbobbin dofi'mg and donning operation. A driver rack is driven by thecycling mechanism and operates a retriever for returning the traversingmember to its starting position, and operates a cutter for cutting thesupply end of the yarn extending to the doffed bobbin. When thetraversing member has been returned to its starting position, the driverrack actuates mechanism to release the jaw operating rod for return toits initial position, permitting the jaws to close on the traverse rod,and the cycling mechanism causes the clutch to again drivingly engagethe drive shaft and spindle shaft whereupon the cycle is repeated.

The patent application is directed to a UNIFIL loom winder which may beoperated at relative high winding speeds, for example 12,500 r.p.m., ormore. In one embodiment, releasable jaws of the traversing member areheld in fixed relationship with each other and are positively threadedlymated with threads of the traverse rod during winding of the bobbin, anda linkage mechanism is actuated by the traversing member, at thetermination of winding, to rotate a non-circular bar extending betweenthe jaws and release the jaws from the traverse rod.

As the winding speed has been increased, it has been found that thelubricant vaporized or was otherwise disapated as it was conveyed to theparts intended to be lubricated. Certain portions of the system had atendency to scatter lubricant and to be displaced out of properadjustment, at higher operating speeds.

It is a primary object of this invention to provide a new and improvedwinder.

Another object is provision of a new and improved high speed automaticwinder.

A further object is provision of a new and improved lubrication systemfor an automatic winder.

Still another object is provision of new and improved apparatus forwinding a bobbin, the apparatus including a casing, a spindle assemblyreceiving the bobbin and including a spindle shaft for rotating thebobbin during winding thereof, provision for rotatably mounting thespindle shaft within the casin g, a lubricant system includingan upperduct in an upper portion of the casing, the upper duct having a portionfor receiving lubricant, and extending from the receiving portion theupper duct having a portion for delivering the lubricant to the spindleshaft, another duct for conveying lubricant to the receiving portion ofthe upper duct and for confining the lubricant, and provision includinga shielded rotary slinger and associated gears for projecting disbursedlubricant through the other duct to the receiving portion of the upperduct for passage of the lubricant from the receiving portion to parts tobe lubricated.

These and other objects and advantages of the invention will be apparentfrom the following description and the accompanying drawings, in which:

FIG. 5 is a fragmentary, schematic, sectional view taken generally alongthe line 5-5 in FIG. 4; and

FIG. 6 is a fragmentary, schematic sectional view taken generally alongthe line 6-6 in FIG. 5.

Various parts of the winder have been omitted in the drawings and insome instances no mention will be made of such omitted parts becausethey are well known from the reference material and are not directlyconcerned with the operation of the portion of the apparatus to bedescribed.

Referring generally to FIGS. 1 and 2 of the drawings, and as is morefully described and shown in the reference material, a winder has arigid base 10 including a housing or casing 12, which encloses drive andcontrol mechanism (FIG. 3) at a rear or inboard end of the base 10, anda tail stock 14 at a forward or outboard end of the base. The casing 12and the tail stock 14 are rigidly connected by suitable structuralmembers, as 16. Bobbin donning apparatus (not shown) receives an emptybobbin from a hopper (not shown) and positions the bobbin with its buttend 17 in an inboard or drive chuck 18 and its tip end 19 in an outboardchuck 20 of a spindle assembly 22 which, through the inboard chuckmember 18, rotates the bobbin for winding a strand of yarn 24 thereon.The drive chuck 18 is connected with a spindle shaft 30 (FIG. 3) withinthe casing 12 and is driven by a suitable motor 32 mounted on aremovable cover 34 bolted to the casing 12. The tip end 19 of the bobbincore 28 is freely rotatable with the outboard chuck 20 which isrotatably mounted on a shaft 38 mounted for axial sliding movement inthe tail stock 14 and is operated by a rod (not shown) connected tomechanisms within the casing 12 for movement between positions holdingthe core 28 (as shown), and for releasing a filled bobbin preparatory toreceiving another empty bobbin core. A spring linkage (not shown) urgesthe outboard chuck 20 toward the drive chuck 18 to clamp the core 28 inwinding position.

As the strand of yarn 24 is wound onto a rotating bobbin, the yarnpasses from a suitable source of supply (not shown) and through a yarnguide eye 40 of a traversing member 42 to build a body of yarn 44 on thecore.

The traversing member 42 is mounted on a track rod 46 journaled at itsopposite ends in the casing 12 and in the tail stock 14. Also, thetraversing member 42 is releasably secured, by means of upper and lowerthreaded jaws 48 and 50 (FIG. 2), respectively, to a threaded traverserod 52 (FIG. 2) which is generally parallel to the track rod 46, and istelescopically journaled in the casing 12 and in the tail stock 14 forrotation and reciprocation by the mechanisms, to be described, withinthe casing 12. The guide eye 40 is in an arm 54 carried by the upper jaw48.

Rotation of the traverse rod 52 during building of the body of yarn 44on the bobbin core 28 provides a builder motion by progressivelythreadedly moving the traversing member 42 from its starting point atthe butt end 17 of the bobbin to a predetermined point proximate the tipend 36 of the bobbin. Reciprocating motion of the traverse rod 52provides a back and forth traversing motion.

As is more fully described in the reference patent application, thepredetermined position at which building of the body of yarn 44 on thebobbin 'core 28 is terminated, is detemiined by an adjustable actuatingmechanism 56 for initiating release of the traversing member jaws 48 and50 from operative threaded engagement with the traverse rod 52, and forinitiating operation of a cycling mechanism (not shown) within thecasing 12. The actuating mechanism 56 includes an actuating unit 58received on a fixed rod 60 for sliding movement as limited by a firstabutment unit 62 adjustably mounted on the rod 60, and a second abutmentunit 64 (FIG. 2) adjustably mounted on the track rod 46. The actuatingunit 58 is resiliently urged toward the first abutment unit 62 by aspring 66 As the traversing member 42 moves to the predeterminedposition at which winding is to be terminated, it repeatedly en gagesthe actuating unit 58 and causes it to move toward the tail stock 14.During such movement, the actuating mechanism releases the track rod 46which then rotates to actuate the cycling mechanism (not shown) as afixed abutment pin 68 on the track rod 46 releases a latch mechanism 70which in turn causes the traversing member jaws 48 and 50 to be releasedfrom the traverse rod 52. Concurrently, the actuating unit 58 ceasesdriven engagement with the traversing member 42 which continues to movetoward the tail stock 1 as the actuating unit is stopped by the block64.

The latch mechanism 70 includes a latch arm 72, fixed to and extendingtransversely from the end of a non-circular bar 74 (FIG. 2) and is urgedupwardly by a tension spring 76 secured to the arm and to a fixedbracket 78 on the winder base 10. The arm 72 is releasably maintained ina latched position by a detent 80 pivoted on a bracket 82 fixed to thebase and urged into a latched position by a tension spring 84 connectedto the detent 80 and to the bracket 82. The detent 80 has a nose 86releasably latched with a cooperating nose 88 on the latch arm 72 duringwinding of the bobbin. An abutment 90 on the detent 80 is engaged by theabutment pin 68 on the track rod 46 to release the latched engagement ofthe detent 80 and the latch arm 72 so that the non-circular bar 74 isrotated to cam-open the traversing member jaws 48 and 50 and to releasethem from threaded engagement with the traverse rod 52.

Resetting of the latch mechanism 70 is accomplished as a driver rack 92,mounted on rollers 94 (FIG. 1, only one visible) and driven through apin and rod 96 by the cycling mechanism (not shown) in the casing 12,moves outwardly in a direction past the tail stock 14 and engages aroller 98 on a crank 100 fixed on a shaft 102 journaled in the tailstock 14. A second crank 104 is also fixed on the shaft 102 and a link1116 is pivoted to the second crank 104 and to the latch arm 72 on thenon-circular rod 74. Thus, the latch am 72 and the noncircular rod 74are rotated and the detent 80 moves into latched engagement with thelatch arm 72.

With reference to FIG. 2, to return the traversing member 42 to itsstarting position proximate the casing 12, a retriever 108 moves betweenthe opened jaws 48 and 50 of the traversing member 42. The retriever 108is on a retriever carrier rack (not shown) mounted in suitable guides(not shown) and is driven through a gear train including a pinion 1 10(FIG. 1) mated with the driver rack 92 to move the retriever from thetail stock 14 to the casing 12, whereupon the retriever is cammed frombetween the traversing member jaws 48 and 50 which then threadedlyengage the traverse rod 52. Concurrently, the filled bobbin is dofi'ed,and the yarn 24 is severed between the traversing member guide eye 40and the bobbin by a cutter 112 which is mounted on a suitably mountedrack (not shown) and driven through a gear train including a pinion 1 14(FIG. 1) mated with the driver rack 92 to move the cutter 112 fromproximate the casing 12 toward the tail stock 14. A scissor 116 on theleading end of the cutter 112 is cammed closed and severs the yarn.Anempty bobbin core 28 is automatically donned and rotation of the drivechuck 22 is thereby started as the driver chuck 18 is telescopedinwardly of the casing 12 and the yarn is automatically engaged with thebutt end of the bobbin core 28 to start the yarn winding onto the bobbincore.

' Outward movement of the driver rack 92 is now reversed and it is movedtoward the casing 12 by the cycling mechanism, thus causing theretriever 108 to be moved toward the tail stock 14 and the cutter 112 tobe moved toward the casing 12 as the scissor is opened.

With reference to FIG. 3, the operating mechanism within the casing 12includes the drive shaft 118 which extends through a rear end wall 120of the casing 12 and carries a belt pulley 121 which is drivinglyconnected by a belt 122 with a similar pulley (not shown) on the shaftof the motor 32 (FIG. 1). The drive shaft 118 is journaled in rotaryball bearings including a rearward bearing 126 seated in a bearingsleeve 128 of a bearing flange 129 secured to the end wall of the casingby bolts 130, and an inner bearing 132 seated in a pedestal mount 134fixed to and extending upwardly from a bottom wall 138 of the casing 12.As will be more fully described later, the spindle shaft 30 of thespindle assembly 22 is axially slidably journaled at a forward end wall140 of the casing 12 and is similarly journaled, within a clutch 142, onthe drive shaft 1 18. The clutch 142 connects the drive shaft 1 18 andthe spindle shaft 30 and this clutch is engagedby inward movement of thespindle shaft 30 responsive to operation of the cycling mechanism whichin turn is operated by the track rod 46, as previously noted, and causesthe outboard chuck 20 to move the bobbin and spindle shaft 30rearwardly. With the clutch 142 engaged during winding of a bobbin, aworm 144 mounted for rotation with the spindle shaft 30 mates with agear 146 to drive a change gear type of variable speed drive (not shown)which in turn drives an intermediate gear 150. The gear 150 drives aspiral gear 152 operatively fixed to a first cam 153 rotatable on thespindle shaft 30 and having a continuous helical slot 154. In FIG. 3 thefollowing structure is displaced from its normal position relative tothe spindle shaft 30 and cam 153 for clearer illustration, and isactually, generally behind the spindle shaft and cam. A follower 155 isreceived in the slot 154 and is on a block 156 suitably mounted forreciprocation generally in the direction of the axis of the traverse rod52. The block 156 has a bore which rotatably receives the traverse rodbetween fixed shoulders 158 thereon for reciprocating the rod andproviding the to and fro motion to the traversing member 42 (FIGS. 1 and2). As will be more fully described later, an oil slinger 160, which ispartially submerged in a sump 162 in the bottom wall 138 of the casing12, is driven by the gear 146 for lubricating portions of the mechanism.A second cam 164 is operatively fixed to the first cam 153, and receivesroller 165 on a first end of a follower lever 166 which is pivotedintermediate its ends by means of a pin 168, to a bracket 167 fixed tothe casing 12 to drive a one way clutch 170 having a housing 172suitably fixed by structural members (not shown) to the casing 12. Theone way clutch has an actuating arm 174 with an elongated slot (notshown) receiving a pin 178, fixed to a second end of the follower lever166, so that as the clutch oscillates, a gear 180, suitably connectedwith the arm 174, is rotated in only one direction. The gear 180 ismated with a gear 182 having a hub 184 formed with a flat telescopicallyreceiving a complementary flat 186 on the end of the traverse rod 52, tothereby rotate the rod and provide the previously noted builder motion.The cycling mechanism is driven, during doffmg and donning operation, bya gear train including a gear 188 meshed with a worm 189 fixed to thedrive shaft 118.

With reference to FIGS. 4-6, in order to lubricate various portions ofthe mechanism within the casing 12, and particularly a spindle shaft andcam bearing 190 joumaled in a member 191 seated in the forward end wall140 of the casing, and thereby the running surfaces of the cam 153 andthe spindle shaft 30, the worm 144 and gear 152, and a bearing 191A inthe clutch 142, the slinger 160 is provided and includes two coaxial,gear-like wheels 192 (FIG. 6) spaced apart by abutting hubs 194. Theslinger wheels 192 and hubs 194 are mounted for rotation on a shaft 196mounted in a pedestal support 198 extending upwardly from the casingbottom wall 138 and rigidly and releasably secured thereto as by a bolt199 (FIG. 6). The slinger 160 is driven through mated engagement withthe gear 146 and is enclosed by a shield 200 (FIGS. 3-6) which confinesthe lubricant picked-up from the sump 162 and deflects the lubricantagainst the rotating gears 146 and 150 and upwardly therefrom. Moreparticularly, the shield 200 is suitably rigidly secured to the pedestalsupport 198 (FIG. 4) and has a straight forward portion 200A extendinginto the sump I62 alongside the slinger 160 with a cylindrical section200B extending upwardly from the portion 200A and closely spaced fromthe gear 150. The shield 200 also has a generally cylindrical rearwardquadrant 200C extending from the slinger 160 and closely spaced aboutthe gear 146. The slinger 160, the gears 146 and 150, and the shield 200provide handling means to receive the lubricant from a source of supplyprovided by the sump 162, and to disburse the lubricant into an atomizedstate and to sling or project the atomized lubricant upwardly through afirst duct 202. The duct 202 is formed by a forward wall 202A andopposed sidewalls 2023, and is substantially open at the rear since theatomized lubricant is directed away from this area.

As the lubricant passes upwardly through the first duct 202, it passesthrough passageways 204 (FIG. 4) in aprons 206 which form a bottom wallof a receiving portion 208 of a second or upper duct 210. From thepassageways the upward movement of the atomized lubricant is stopped bya top wall 212 of the second duct 210. The wall 212 is suitably fixedlysecured to the bracket 167 and interconnects upper end portions of thesidewalls 202B which form part of the receiving portion 208. Within thesecond duct 210 the lubricant drops onto the aprons 206 which declinetoward the forward wall 202A and toward a first channel 214 between theaprons. The channel 214 also declines toward the forward wall 202A. Theaprons and channel are fixed to the top wall 212 in any suitable manneras by welding. At its lower-end, the channel communicates with adischarge portion 216 extending through an opening in the forward wall.The discharge portion 216 is fixedly secured, as by welding, to the topwall 212 and overlies a delivering portion 218 (FIGS. 4 and 5) of thesecond duct 210 for passage of the lubricant from the first channel 214to a second channel 220 of the delivering portion. By removing a bolt220A extending through a hole in the bracket 167 and threaded into thetop of the pedestal support 198, the first duct 202 and the receivingportion 208 of the upper duct 210 may be removed as a unit, whileleaving the delivering portion 218 of the second duct intact.

The delivering portion 218 of the second duct 210 has a rigid flange 221which is adjustably and operatively fixed to a flange 222 of a fixed,rigid bracket 224 by means of bolts 225 extending through horizontallyelongated slots in the flange 221 and threaded into the flange 222. Thebracket 224 is fixedly secured to the adjacent end wall 140 of thecasing 12 by means of removable fasteners 228.

Lubricant delivered to the delivering portion 218 of the upper duct 210flows into a receiver 230 which communicates with a spiral passage orgroove 231 (FIG. 5) in the outer face of the bearing and with a passage232 opening into the groove and extending through the bearing 190, fromwhich the lubricant flows along the spindle shaft 30 and through aspiral passage or groove 234 in the inner surface of the bearing 190 andinto a chamber 236. From this chamber the lubricant flows through aradial passage 238 in the spindle shaft and into an axial passage 240 tolubricate the clutch bearing 191A, and from the axial passage 240through radial passages 242 and 244 to lubricate the spiral gear 152 andthe worm 144, respectively.
